Transistor 2SB189 PNP, 25V TO-1
The 2SB189 is a classic PNP Germanium Transistor in a TO-1 metal can package. Purpose-built for vintage radio and amplifier repairs, it delivers the warm signal characteristics and reliability that defined mid-20th century electronics.
2SB189 Germanium PNP Transistor – Classic Part for Vintage Audio Restoration
The 2SB189 is a PNP germanium transistor recognized for its role in vintage radio and audio equipment. With a maximum collector–emitter voltage of 25V and a metal can TO-1 package, it remains a trusted choice for restoring classic audio circuits and ensuring historical equipment continues to function with authentic component replacements.
Functions & Applications
- Germanium Construction: Authentic replacement for vintage radios, amplifiers, and audio equipment from the 1960s–1980s.
- Classic TO-1 Package: Distinctive metal can design, period-correct for vintage circuit restoration.
- 25V Rating: Suitable for low-voltage vintage audio and radio circuits.
- Warm Sonic Character: Germanium transistors are prized in audio restoration for their natural signal response and smooth distortion characteristics.

Frequently Asked Questions
Q: Can I use the 2SB189 in modern circuits?
A: The 2SB189 is specifically designed for vintage equipment repair. While it can work in modern designs, its germanium construction and lower frequency response make it unsuitable for contemporary high-speed applications. Its primary value lies in authentic restoration of classic radios and amplifiers.
Q: What is the complementary NPN germanium transistor?
A: The complementary NPN germanium transistor for the 2SB189 is the 2SA100 or 2SA101, depending on the specific circuit and era of equipment.
Notes
Vintage NOS (New Old Stock) germanium transistor. Values may vary slightly between manufacturing batches due to germanium's temperature sensitivity. Not suitable for modern high-frequency applications; reserved for authentic vintage restoration.
Note: Price refers to one (1) piece. The component is shipped in bulk without individual packaging.
